This thread is just a quick lesson in you get what you pay for.

While cleaning my "Z Works" as I like to call it today in preparation for another glorious weekend in the mud and has only seen 3 weekends of serious mtb use, I found it is broken As you can see in the picture it's the seat stay but at least it it wasn't the steerer tube which I did think about while riding landing jumps and it didn't explode as people think carbon frames do.

It looks like something hit the stay and can only think the bike fell on something while stationary, I've not had a crash yet "amazingly" and not been aware of the bike falling on anything except flat ground. So it looks like I'm up for a new frame, in another thread I said if I broke it I would just buy another but if china carbon frames only last 3 weekends it's an expensive way to go. I think I'll get an alloy FS frame next.
